My improvements relate particularly to the extractor mechanisms ofrevolving firearms of the kind patented to C. A. King August 24, 1869,No. 94,003.

The barrel 1 of the arm is pivoted to the frame 2, so as to carry thelifter 3 in the joint. The finger 4 of the lifter bears against the endof the rod. 5, to which the extractor 6 is attached at the other end.The cylinder 7 is supported upon the tubular pin 8, fixed in the 6barrel, and the extractor is retracted into the same, in the usualmanner, by a spiral spring around its stem or rod 5. The constructionand operation of these parts are well known, and will be readilyunderstood without further description.

The extractor-lifter 3 is made in the form of a ring, Figs. 3 and 4,having the notch 9 on its inside edge. when in place in the joint of thearm, this ring 3 is mounted upon the hub 10, on which it is free torevolve, as herein after described. The hub 10 is a more onlargement ofthe joint-pin 11 of the arm where it surrounds the same, and it issecured to the leaf 12 of the frame part of the-joint by the So screw13,whicl1 enters the hole 14 in the hub, Figs. 1, 5, and 16. The framecarries the outside leaves, 12 and 15,0f thejoint,and the barrel theinside leaves, 16 and 17, of the usual construction, and theextractor-lifter revolves between the latter. In order to get the hub 10into its place in the joint around the pin 11, the leaf 16 of the barrelpart is bored out the size of the hub, while the opposite leaf isconcentrically bored the size of the axial pin 0 11. The lifter 3 isthen slipped edgewise into place between the barrel joint-leaves 16 and17, and the hub 10 is passed sidewise through leaf 16 and the lifter.The leaves 12 and 15 of the frame part of the joint are now slipped intoplace outside of the barrel parts of it, and the axial pin 11 insertedin the usual way. The screw 13 is inserted through leaf 12 into hole 14in the hub and thejoint is complete.

It will now be seen that the hub 10 always travels with the leaf12 ofthe frame and axial pin 11 and forms an enlargement of the pin,

around which leaf 16 of the barrel and the lifter revolves, while leaf17 of the barrel rcvolves directly upon the pin 11. If this were all ofthe construction of the parts, the lifter would simply revolve aroundthe hub and have no means of actuating it to force outthe extractor; butthe alternating action of locking the lifter 3 to the hub 10 andreleasing it after the extractor has ejected the cartridges isaccomplished in the following manner:

Across the face of hub 10, which rests against the inner face of barreljoint-leaf 17, is cut a slot, 13, at right angles to the axis of thehub. In this slot is fitted a sliding latch, 19, made as long as thediameter of the hub 10. One end of this latch is formed into asquareedged nose, 20, capable of entering into the notch 9 of the lifter3, and thus locking the lifter and hub 10 together. The latch 19 is alittle wider at the other end than its groove 18 in hub 10, and has aslot, 21, cut through it to allow it to be sprung together and have africtional bearing in the hub. The latch 19 also has the elongated hole22 through it, to allow it to slide in the hub to and fro around thejoint-pin 1.1,which passes through it. To properly move this latchinlocking and unlocking the lifter 3 a pin part, 23, projects outward fromits face into a curved slot, 24, in the barreljoint-leaf17, Fig. 11.This curved slot is of a sufficient breadth radially to the joint= axisto allow the pin part 23 to travel around in it whether the slide 19 bepushed out into the lifter 3 or drawn entirely back into the hub 10, andit has a cam-shaped bevel, 25, at one end of it, which, coming intocontact with the pin 23,will push the latch 19 into the hub 10, andanother curved slot, 26, at the other end, which, coming into contactwith pin part 23, will push the latch out into the notch 9 in the lifter3. in dotted lines in Figs. 9 and 17.

The operation of the mechanism is as follows, the parts having been puttogether, as before described, with the latch 19 in its place in hub 10:XVhen the arm is closed, as shown in Fig. 9, the cam-shoulder 26 of slot24 in leaf 17 comes into contact with pin part 23. of latch 19 andpushes the nose of the latch outward into notch 9 in the lifter 3. Thelifter is now locked to the hub 10 and frame 2. When the parts are swunginto the position shown in Figs. 1 and 2, the continued movement ofopening the pistol will cause the finger 4 of the lifter to force outthe extractor. XVhen the barrel has been completely opened and thelifter has done its work, the cam-shoulder 25 strikes pin 23 andwithdraws latch 19 into hub 10. This releases the lifter 3 from the huband the extractor-spring causes the lifter to revolve backward aroundthe hub to the position shown in Fig. 1 with relation to the barrel. Theclosing of the arm repeats the movements, as before described.

Figs. 10 to 17 show the additional feature of a cam added to the device,whereby the barrel of the pistol may be opened and swung The position ofthese parts is shown down without extracting the cartridges in case itis desired to inspect them before discharging the pistol. of thethickness of the annular part of the lifter is removed and the disk 27,of proper thickness to fill up this part cut away, is in troducedbetween thelifter and barrel jointleaf17, the hub 10 being alsoshortened sufficiently to admit the disk. This disk27 revolves on thejoint pin 11, which passes through its central hole, 28, and it hasaspur, 80, on its periphery to turn it by with the finger. Through it,opposite to the slot 24 in the barrel hinge leaf 17, is cut a slot, 29,to allow the pin part 23 of the latch 19 to pass through the disk intothe slot 24, as before described, and as shown in section in Fig. 16. Onone side of the slot 29 it terminates in a cam-shaped bevel, 31, soproportioned that when the disk 27 is revolved and this bevel is broughtagainst the pin part 23 of latch 19, as shown in Figs. 1.4 and 17, thelatch will be pushed into the hub 10 and the lifter unlocked therefrom.

When it is desired to open the barrel without extracting the cartridges,the barrel is to be opened as far as shown in Fig. 1 and the disk 27turned by the spur 30 from the position of Fig. 14 to that of Fig. 17,which withdraws the latch 19 into hub 10, and the arm may continue to beopened withoutoperating the extractor-lifter.

In case the disk 27 is not moved the operation of thelifter and itsrelease will be effected precisely as before, as the disk can neveroperate to unlock the lifter automatically. The disk 27 might be made torevolve around the hub 10 and have bevels or spurs to operate on the endof latch 19, if desired, instead of against the pin part of it.

Figs. 18 to 28, inclusive, show another form of unlocking device for theextractor-lifter. In this construction all the parts are similar tothose first described, except the pivot-pin 11 and the hole 22 throughslide 19, the latter being made square at one end instead of oval. Thepivot-pin is made tubular with its head countersunk. Through its wall,across one side, is cut the slot transversely. From this thelongitudinal slot 36 is cut through its wall toward its head. The slot05 is opposite the slide 19 in the joint and allows the square end ofhole 22 in the latter to enter it, as shown in Fig. 23. The plunger 37is introduced into the pivot-pin 11, as shown, and the steel cam-piece38 is slipped into the mortise 39 in the plunger, thus securing thelatter into the pivot-pin 11. The pivot-pin being inserted through thehub 10, the cam-piece cannot escape. The screw 41 is then screwed intothe open point end of the pivotpin 11, with the spiral spring 42 betweenit and the plunger 37, thus securing the parts together. When it isdesired to draw back the latch 19 into hub 10, the outer end of plunger37 is pressed upon by the finger and the bevel of the cam-piece 38forced against the square side In this construction a portion ICC) ofthe hole 22 in the latch 19, thus unlocking the lifter from the hub andpreventing its acting upon the extractor. It will be observed that inthis construction of the latch for lock ing the lifter to the frame part2 of the arm the latch is operated in both directions by cam-shoulderson the barrel part of the arm, while it is mounted in and carried by theframe part 2 thereof, the hub 10, in which it works, being but anattachment to the latter. By my change in the location of the latch 19and operating it positively in both directions by the camshoulders 25and 26 of the barrel part of the arm I am not only able to dispense withany spring to operate it, but I inclose it entirely within the lifterand leave no joint exposed to being fouled up by dirt or gases of powderaround it, and the construction is neater and better than when the latchis exposed at either one or both ends during its operation.
